Kerby-Fulton also narrates success stories of intellectual freedom, tracing evidence of ecclesiastical tolerance of revelation, the impossibility of official censorship in a manuscript culture, and the powerful, protected reading circles for radical apocalypticism and mysticism, such as those of the Austins and the Carthusians. Until now, Wycliffism has been seen as the only significant unorthodox or radical body of writings in late medieval England. Books under Suspicion is the first comprehensive study of banned non-Wycliffite materials in Insular writing during the period of the Avignon and Great Schism papacies. This weighty, complex, and rewarding book makes use of neglected material in manuscripts and archives to reconstruct new aspects of the history of religious thought and vernacular writing in Ricardian and early Lancastrian England. As such it will interest scholars of late medieval religious history and Middle English literary history.
